This -.invention.. relates I to, v machines for I forming upstrandmaterial: fromfiat paper strips-orthe'like. It'is more particularlyconcerned with that portion. of the -mecha-.

nismby .which the strip material,isftreated' 0 uing substantiallycontinuously.

One of the objects of this lnvention to provide a glue circulatingsystem which will insure a constant supply "of glue properly Iconditioned for use to" all the strips? Forthis purpose I provideanelevated tank for:

the 'glue from whichit'flows by gravity to preferably a' pair ofdownwardly inclined troughs to each of whichpaper strips are' scale online 3 -3 oflTigure 1. M

' ,Figure 4 shows in perspective a drive for guidinga strip of I passedon th eir "way to the twisting mechanisms. ,Fromthe lower ends .of'thetreating I troughs the glue flows throughp'ipesto a-pair of lowerdrain troughs inclined in the oppo.

site direction from :thelower'ends of which Figure 4.

Referring to the glue flows into a heated supply tank. The

glue is pumped from the supply tank tothe elevated tank. By the. useiofthe elevated tank feeding by gravity tothe uppertreating troughs, theflow. to theselatroughs may; be-

regulated as desiredfindependently of the tank so long as the pumpisadequate to meet maximum requirements, any excess of glue 7 suppliedby-the pump to the'elevated tank being automatically returned therefromthrough an overflow pipe to -the supply tank, thusto govern thepermissive heightof glue in the elevated tank; The elevated tank acts:also as an emergency. supply which perm continued operationot thein'achine' for a time 7 ,from time to time beflinecessary at least forshort periods. -Prefer'ably the elevatedi'as well asathe lower tank areprovided with heat The, strips paper in roll form "are. posit'ioned'abovejthe treating troughs where there 7 is-ample room iorilarge rolls.

the shutting down of the apparatus. Such shutting down is troublesome asthe -glue soon 'hardens and clogs the mechanism when it is notkeptin'circulation. 7 i

The device forcausing the paper strips to pass through the glue in thetreating troughs is preferably formed as shown in detail in Figures tand5. Referring to thes'e iigures, indicates a pair of spaced supportingbars joined at one end by a plate 51 which may, if

desired, be fiXedto oneof the supports 30." At

theirother ends the bars 50 are joinedby a rod 52 overwhich the paperpasses on its Way to the, mandrel 36. 'Positioned between the-Tsupporting bars 50 is a frame comprising f 'pairofsidebars 55 and56'joinedi at oneend' by a-rod 57 which in theoperation'ofthe; de-
